There have been a few ukuleles using the name ‘Hilo’ over the years. The most common one now is based on the island of Hilo, Hawaii (although the ukuleles themselves are made in China). All the advertising I’ve seen for them say the company was founded in 1926. But for a company that old, there’s not much information on them around.
